Answer: carbon dioxide and water
Explanation: hydrocarbons are compounds of carbon and hydrogen. Combustion is another word for oxidation. Oxygen splits, the CH bonds, oxidising both the C and the H. The simplest hydrocarbons, the alkanes, have the general formula C(n)H(n+2)
The combustion reaction is
(3n+1)O2 + 2C(n)H(2n+2) —> 2nCO2 + (2n+2)H2O
Rubber is not very good at conducting electricity. This is because rubber makes it difficult for electrons to flow between atoms, due to rubber having tightly packed electrons. Materials like rubber are known as insulators.
Conductors are the opposite, they conduct electricity very well. Examples of conductors are metal, which is why metal is used in wires.
Since rubber is not a conductor, answer choice B can be eliminated. This can also eliminate answer choice D, since insulators like rubber don't allow electricity to easily flow.
While rubber gloves keep our hands dry, there are no liquids involved in this experiment and this is not the main reason for using rubber gloves. This eliminates answer choice C.
The answer is A. rubber gloves are insulators.
The teacher instructs the students to wear rubber gloves to prevent them from getting an electric shock.
Answer:
A. rubber gloves are insulators
Hope this helps!
Answer:
A. ionizing energy increases
Answer: The atomic number
<span>The answer is Mandy’s solution is a
Base/Alkaline solution. Alkaline solution turns
red litmus blue while acidic solution turns
blue litmus red. In acidic solution, the red litmus remains red while in
alkaline solution, the blue litmus remains blue. However, litmus paper can never tell you the exact pH
number of a solution</span>
